If the child’s environment contains relationship models of domination and hierarchy (disrespect, yelling, or violence), that child’s brain, being an amazingly adaptive organ, will grow in ways that will specialize itself, chemically and structurally, for hostile or threatening environments, developing greater vigilance, greater suspicion, more self-protective perspectives and behaviors. The unfortunate side effect of this specialization is the disabling of the brain’s social capacity for trusting, peaceful, cooperative living.
